3 Claims. (01130-273) I The present invention is directed toimprovements in portable air conditioning fans, and more particularly toone designed to be'placed on a heating unit, such for instance as a gasheater,

hot air register or a radiator.

The primary object of the invention is to provide a device of thischaracter so constructed that when placed on a heating unit the heatedair rising therefrom will propel the fan with sufiicient velocity todraw air from all parts of the room in which it is placed, and fromadjacent rooms, the air thus drawn being subjected to the action of thefan to cause circulation thereof to condition the same.

Another object of the invention is to provide a device of this kindwhich is extremely simple in construction, efficient in operation, andone which can be manufactured at a small cost.

With these and other objects in view, this in- 20 vention resides in thenovel features of construction, formation, combination and arrangementof parts to be hereinafter more fully described, claimed, andillustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of the device.

Figure 2 is a top plan view thereof.

Figure 3 is a perspective view of the device, the fan being removed.

Figure 4 is a vertical sectional view through the device.

Figure 5 is a sectional view on line 55 of Fig. 1.

Referring to the drawings, designates a base formed from suitable gaugesheet metal, the base 35 being hollow to constitute a fresh air chamber2, fresh air being admitted to the chamber through openings 3 formed inthe side walls 4 of the base.

The top 5 of the base is provided with a cen- 40 trally located opening6, and into which is fitted the lower end of a collar 1. This collar isretained in place by a pair of brackets 8 consisting of angularlydisposed arms 9 and H], the former being secured to the top 5 by bolts45 while the latter are extended into the collar and are secured theretoby rivets l2.

A sleeve I3 is removably engaged on the collar 7, the lower end thereofresting on the top 5, said sleeve being of greater length than thecollar, and constitutes an air discharging duct.

Extending transversely of the sleeve l3, and near the top thereof is abar |4 having hooks IS on its ends adapted to fit on the upper edge ofthe sleeve, the arms I6 thereof resting against the 'innensurfaceofthefsleeve while the arms 1 1' lie against the outer surface thereof.

sr ecor'rd.bar -|8 is "employed and has down turned .ends IS. The endsof this bar rest on the hooks l5 and the terminals or ends |9 restagainst the arms l1, and securing devices are passed through the endsl9, arms I1 and sleeve l3 to hold the parts in assembled relationship.

The bar I4 is provided with a central opening 2|, and through whichextends the shank of the pin 22, the head 23 thereof serving to preventupward movement of the pin. To retain the pin 22 in true perpendicularposition a metal strip 24 is employed and has its ends riveted to theundersurface of the bar M in order that the head 23 will be firmlyengaged by the strip to retain the pin in place.

The pin 22 extends through a bearing 25 formed centrally in the bar l8and is in direct alinement with the opening 2| of the bar M in orderthat the bar l8 will effectively brace the pin to maintain the same invertical position.

The fan 26 includes a hub 21 and. integral blades 28, there being anopening 29 in the hub which coincides with an opening'3ll formed in theplate 3|, said plate engaging the under surface of the hub to brace thesame.

An inverted sheet metal cup 32 is employed and has a flange 33 adaptedto rest on the hub 21, said cup being fitted in an opening 34 formed inthe top plate 35, said plate being secured to the flange 33, hub 21 andplate 3| by rivets 36, additional rivets 31 being used to secure themargin of the plate 35 to the hub 21 and plate 3|.

In the top of the cup 32 is fixed a shank 38 having a head 39 on itslower end, said shank and head being formed from hardened steel, thepurpose of which will be obvious as the description proceeds.

A sheet metal partition 40 is suitably fixed in the cup 32, and isprovided with a central opening 4| alined with the openings 29 and 3|]of the hub 21 and plate 3|, respectively. The partition provides agrease chamber 42 within the cup, grease being introduced thereintothrough openings 43 in said cup.

As clearly shown in Fig. 5 of the drawings the pin 22 extends throughthe openings 30, 29 and 4| and its pointed end engages the head 39, dueto which resistance to rotation of the fan 26 is practically nil.

The presence of the grease chamber 43 assures proper lubrication of thepin 22, and the fact that the pin is engaged in the opening 4| of thepartition 40 aids in balancing the fan 26 on said pin.

The fan 26 can be easily removed from the pin 22 when desired andreplaced thereon easily and quickly.

Briefly the operation is as follows:

Heat rising from the unit upon which the base I is placed will propelthefan, and during the propulsion thereof air from the room in which thedevice is located will be drawn through the openings 3 and will enterthebase and then flow upwardly in the sleeve I3 for discharge from theupper end thereof. In this manner the fan will, agitate the air tocondition the same by thor-' low base, a sleeve supported thereon, a pinsupough circulation.

What is claimed is:

1. A portable air conditioner comp-rising" ahol-' low base, a collarsupported by. the-base, a sleeve supported by the base and encirclingthe collar, said collar and sleeve communicating'with the interior ofthe base, upper and lower. vertically spaced bars supported by thesleeve and disposed transversely thereof, a pin having its lower endengaged with the lowermost bar and extending through the upper bar, afan having a cup fixed to its hub, a partition in the cup to define achamber therein, a head in the chamber, said pin passing through thepartition and rotatably engaged with said head.

2. A portable air conditioner comprising a hollow base, a sleevesupported thereon, a pin supported axially of the sleeve, a fan havingan inverted cup fixed to its hub, a partition in the cup defining achamber therein, said pin passing through the hub and partition forrotatably engaging the cup.

'3. A portable air conditioner comprising a holported axially of thesleeve, a fan having an inverted cup fixed to its hub, a partition inthe cup defining a chamber therein, said pin passing BENJAMIN C.BARTLEBAUGH.
